Balhalla is apparently an afterlife that Shamir Shamazel believed in. He thanked Balhalla that Alexander became his new master.
Behind the scenesEdit
Balhalla in some contexts is an alternative spelling for Valhalla. It is spelled with a B but sounds like "Valhalla". However, Valhalla a nordic and viking afterlife which doesn't seem to fit into the theme of KQ6 in any way. Valhall is the hall of the slain within Asgard.
Possibly a reference to the idiom, "Thank, Heavens".
There is a Balhalla island near Borneo.
