Gunther had an apartment in Haddyn in the 23rd century. It had an aquarium for him to stay in and visitors would walk over the glass, communicating through an intercom.[1]Melaka once broke the glass to fight underwater and kill Urkonn of the D'Avvrus, who didn't know how to swim.[2]
In the new timeline formed after the Reckoning, Gunther lived in the same apartment, but he did not recognize Melaka.[3]
