The river that cascades in a waterfall over the edge is responsible for the high number of caves and erosion in the interior of the crater. Eventually the north wall of the crater collapsed giving the opening to the sea.

2. Dolphin Hall
Situated on a small natural lagoon that is protected, though the Hold itself is somewhat exposed, the Dolphin Hall has easy access to the great Southern Currents that sweep the ships in towards Arolos Bay. More detailshere

3.Thonet Hold
A relatively small fishing hold but often used as a drumming point and trade stop on the coastal trade routes. It has a sheltered cove that produces marvellous Ormoler shells that are highly prized and jealously guarded.

4.Motheno Hold
A Hold on the edges of the deep forest and with access to the massive plains below the foothills of the mountains. A wild pioneering hold and often used by traders as a way point and base camp for collecting hides, rarities and products from the rich south. More of a trading post than a real Hold. However, the area near the mountains is rich in many ores minerals and gems, IF people care to risk the wildlife and rough lifestyle

5 Wabonel Hold, Forest Edge Hold and Weaver Hall
This collection of Holds is highly dependant on the Smithcraft operation opposite...and the the Smithcraft dependant on them for labour. In the wash from the mountains are gems and ore..and the river is used in processing it and assisting in Smith mining operation.

The lands of Wabonel have a rich deposit of coal which is vital to the area's need and the Minecrafters at the Smith hall contract to mine there.

Forest Edge concentrates on suppling the needs of this area and the Weaver craft hall gets many of its pigments from the ore processing and makes some of the finest coloured weaves on Pern.

7. Estuary Hold.
Keeps the main Bridge and Lock for the Coastal Trade Route and harvests numbweed and medicinal plants for trade. Has a cooking specialty of watersnake stew which apparently is delicious.

8. River Mouth Hold.
A vital hold as the product of the Smithcraft and inland holds are shipped down river to this port. Often then it is shipped by skiff to Arolos Hold which is the main port, but it is small but busy holding.

9. Alonel Hold.
Is a river side hold with a lush grassland behind it, backing up to the mountian and foothills. It tends to have a temperate climate as the clouds condense and fall mainly in the rainforest in the lower mountains rather than directly over the hold proper. They have the option of bringing in mustang runners that roam the plains and have a great deal of success growing ornamental and medicinal plants. Alonel maintains close links with Callamere Beast hold.

10. Callemere Beast Hold
A very favourable site next to a fine inland lake and forest, and grassland allowing for a great deal of variety in the beasts that are bred there. Callamere White runners, meat-type erdbeasts, wherries, Callamere whers and... just about anything else are to be found here...

11. Arolos Cotholds - Affliated with Arolos Hold
Many small Cotholds, including Arolos Point Hold..which is directly beneath the Cliff that extends from the Weyr Rim to Arolos Point.

On Arolos Point is a Beacon Fire that warns ships of their proximity to shore whilst navigating the current coming into the Bay.

12. Arolos Hold.
The main Trade centre of this area of the south. It is the main seaport to the North so trade inevitable is shipped in, and out of here. It has a enviable position and Holders in this region are beholden to the Lord Holder.. or basically they have to find their own way to get supplies.

It lies on Arolos Bay, a protected safe harbor due to its circular shape...coming from it once being a volcanic crater. It has a view of the Bay and Arolos Island...as yet undeveloped.

13. Healer Hall
As close as possible to the source of main supplies and transport for obvious reasons.

14. Reddan Hold
The priciple grower of fruits and brewers of fine wines as there is plenty of irrigation and open sunlight. Currently experimenting with their own version a Benden sparkling white.

15. Harper Hall
Again because near communication source and because this is the highest population centre. Journeymen can go off to Holds from here but this is their base.

16. Seacrafters Hall
For obvious reasons. There is a natural harbour here and even a sea cave large enough to shelter some of the small fishing fleet during thread, so they can set to sail immediately after Fall for a bonanza catch.

17 Island View Hold
Bridges the pennisula and has a harbour on the ocean side for excursions further down the coast.

18. River Point Hold.
Owing to the river canyon and chasm that splits the land here, River Point control the bridge and the trade route along the coast to the West. Many of the holds to the West have to ship good through there to Arolos Hold or down the river.

19. Startol Hold.
Situated on a small river tributrary that sometimes dries up.... Often sends people to the Inland Great Lake to supplement their goods and supplies.

20. Verd Hold
A forest hold, making a living out of timbers that they ship downriver.

21. Woodcraft Hall
Season and manufactures wooden products out of the rare hardwoods of the south and sends down to the Holds in that bay.

22. Dollanol Hold
Main shipping point for the West side of this area

23. Atoll Hold
Makes a surpisingly good living with harvesting corals, and pearls. The reef is treacherous to all but small ships but plentiful in fish and giant shellfish.

24. West Bay Hold.
Again a new hold set up as an extended traders stop.

25. Minecraft Hall
Currently mining an extensive firestone desposit and flourishing. The region depends on this for firestone and as such for all its distance it is a frequent point for dragonriders on a direct pick up.

26. Pyran Hold
And when the dragons do not do directly pick up, the firestone and other products are shipped to Pyran and distributed from this point.

There is a thick band of forest that makes further exporation difficult but there are numbweed plains in the lee of the mountains and there is the occasional isolated Hold trying to start up from this point in.
