When I was playing my second run of EA, I just figure out that the different portals should potentially allow you to return to one location of the chapter 1.
If I refer to my experience with DOS 2, leaving the chapter is closing definitly the access to the map from this chapter.

Again a story a boat wink

But anyway, from a functional point of view, getting access to a small part of map from chapter 1 should be possible through the portal. And we have already in this area some nice locations for a stronghold to be established.
What i call stronghold is like a permanent base which can established by the PCs, which can be improved with new areas, features and potentially hosting some NPC for specific tasks (like guards, merchants, artisans, refugee, animals , etc).
Getting a stronghold is a major quest and can trigger a bunch of small quests according to the location. Here are some examples :


Rebuilding the Waukyne Rest.

=> Recruit staff, guards, specialist merchant (cooker), musicians.

=> Small quests can be established related to travellers.

=> Inn can be also randomly attacked by raiders.

=> Once rebuild, you gain money from the inn.

=> You have to provide or invest on some stuff for the inn to work efficiently.


Rebuilding the ruined village.

=> Recruit new citizens including tieflings from camp.

=> Small quests can be established related to travellers.

=> Village can be also randomly attacked by raiders.

=> Quest to move the portal stone outside of the village (too dangerous inside)


Cavern in Druid camp.

=> The cavern used by Zevellor can be allowed to be used by the party.


Selune Temple.

Can be transformed into a temple for another deity or be used to do what you want in fact 😊.

=> Recruit staff, guards, trainers, merchants

=> Small quests can be established related to travellers.

=> Temple can be also attacked by raiders.

=> Guards can securize weak points

=> Old goblin camp can be transformed as optional village.


Arcanic tower (since it appears it is not occupied)

=> Hire masons to repair the floors.

=> Bernard could be a perfect steward for this place. (Bernard is a reference to Westworld, doesn't it ?)

=> Arcanic tower could not reveal all of these secrets. It seems it can move. Is it possible to move it outside the UnderDark ?


Abandonned village in Underdark
(place is incredibly beautiful but a poor choice for a lair since not easy defendable).

=> An house can be offered by the gnomes after delivering them.

=> Gnomes can also prepare a cavern near the village for you that you can customize. Including the shining stones or luminous mushrooms.

=> Recruit staff, guards, merchants (especially gnomes and Seldarin drows)

=> Improve defense of the village

=> Village and stronghold can be attacked by different packs and creatures

Gnoll cavern.
=> Can be transformed into a cozy underground place.

Owlbear cavern.
Can be transformed into a cozy underground place.

Selune 's outpost in Underdark
Can be transformed into a cozy underground place.

Zhentarim cavern
(if you become a Zhentarim friend or not ; in this case, Zhentarims can send increasing forces to take back the place)

Lof of work to do that for sure but what do you think about this idea ?
