Doubt it'd be another maze I quite like puzzling quests though such as MEP2, WGS, Seren sure liked her freaky temples of light. Wait, Seren built the Temple of Light? I'm fairly certain MEP3 will take us into Priffdinias, with some sort of crystal-themed maze there. Maybe parts of the ground where you can't run, and can't be over a certain weight? Or better yet we get an awesome looking, yet useless piece of junk like the Fixed Device/Bazooka. No Idea if she build them she built Prifddinnas, 8 Clans of elves, think its on page 3 of this thread I quoted the book, theres also another book on the alliance between humans and gnomes and elves, not sure if seren was alive for the temple building, but she has contact through the "Tower of Voice" where she communicates to the elves through, or atleast thats my interpretation. Can't say what'll happen in MEP3 because it could be anything I do think the rewards will be really good, and I definately would say Prifddinas is a certainty since it's been there 4 years.
