To progress in act 2, i NEED to pay for the library?

[Question]

As title. You need to talk to Aldanon after the Arvahn quest, but hes not in the keep as far as i can tell unless you pay for the library....

I'm not sure, as by that time, I have already built the Library, since I usually don't know on what else to spend the money for ...;)

This gets a little confusing, but here goes.

After you return from the Ruins of Arvahn, Aldanon appears in the ante room just outside the library and tells you about the Haven, NOT in the library per se. The ante room is the room between the library and main hall. See the map in the Locations of the Keep section for details.

In Act 3 after you return from the Haven, ALdanon appears in the library itself.

I always wait until KT freezes at 25 before I go to the ruins of Arvahn - so that ensures that everything I CAN build in Act 2 IS built including the Library.

HOWEVER, there is a well know exploit that actually builds the Library for you for FREE if it hasn't been built by the time you return from Jerro's Haven which triggers the start of Act 3. This exploit appears to exist even after the latest patch.

If you are actually having a problem and he is NOT appearing after you return from the Haven, then a script is failing to fire and you need to reload from an earlier save. Otherwise, building the Library is NOT required to have him appear after the Ruins.

Thats weird, he didnt appear in the ante-room. But i just built the library and that fixed it.
