This is a Rotkan visa stamp, written in the High Galactic alphabet, as it appears on an Intergalactic Passport. Rotkan, a place within the galaxy, housed the Euclidean Complex. To gain entry into Rotkan, individuals were required to possess visas officially stamped within their Intergalactic Passports, and they also needed to be escorted by guides at all times. It is a known fact that Rotkan, at some point, employed a calendar system distinct from the Galactic Standard Calendar.
