Hmmmm. Interesting Q, Kevin. I think the Q is a bit vague, and since the stone is intelligent, it could prompt the PC to clarify his Q/intentions before answering. On the answer front, I think at least part of the answer will vary if you are running just the core 3 levels from WG5 or are planning to use the new levels as well:
- If the scope of the Q is just the original 3 levels, and if you're not going to crock him on the Q in terms of providing a philosophical vs. useful answer ("
you will make you the most powerful" or "
not dying in the dungeon will make you the most powerful" or whatever), then I think I'd go with "Travelling to the Lost City of the Elders" as the response, since successfully using the tapestry for transportation to the LCotE will require the PCs to defeat Kertiz and Eli and acquire the Tome of the Black Heart, and that will take the PCs on to another adventure area.
- If the scope of the Q is the original 3 levels + the new levels as well (Statuary, Chambers of Antiquities, Greater Halls, Warlock's Walk), then I'd reply with "Looting the Chambers of Antiquities"
