The great elven city has remained fairly secluded since the Conjunction. Only recently have outsiders been traveling to the city for business. The elves and eladrin welcome the newcomers, often seeking information on the world beyond their forest. The city is difficult to find, and without aid from its denizens travelers could wander for days lost in the trees. The city itself sits atop a lake, with much of the city rising above the waters in massive spires.
Cellysio is also rumored to hold and control the only know Fey-Crossing. A consistent gate between Earthynn and the Feywild. The Fey-Crossing also inhabits the the forest with all manner of creatures from this wild realm.
