Trey seems to be having trouble getting some work done, mostly because he has lost a super important memolith. He mentions that someone named Wally over at the Smartstick Lab might have it, which is on the second floor of the factory. Teleport to Dynafloor No. 1, then make your way to the second floor, where the Smartstick Lab is on the way to the third floor. Unfortunately, Wally doesn’t have the memolith anymore, as he lent it to Tad, who should be hanging around the reactor control room.

Getting Trey’s memolith back will set you back 10,000 guilders

Teleport to the Cradle of Wisdom next, then use the elevator to go down to the Reactor Floor. Speak to Tad in the control room, who sold the memolith for some cash. Bracken deduces it was sold to Poplar Produce, which is in Lower Downtown, so that’s your next destination. Peruse the wares to see Trey’s Missing Memolith at the bottom, which costs 10,000G. Purchase it, then bring it back to Trey to finish the quest.
