Interdimensional Ham Radio
The Interdimensional Ham Radio, or I.H.R., was a device created by the 775th Universe's Laura Drake at some point before she completed her first physical interdimensional portal, the Triangular Bisector.
After Lord Grallyx's emergence damaged the Bisector, Laura killed time by “playing” with the Radio again. It started spitting out questions from “interdimensional busybodies” who'd apparently been watching Jenny and Laura's adventures, which she started answering, keen to keep them talking. At one point, they received a question from an interdimensional observer inquiring as to the name of the universe in which the two resided. Before Laura could answer, the I.H.R. she was using spontaneously put her through to the Multidimensional Finders Service, and a bored-looking Jenny Over-There informed her that her universe was “Reality #775” before hanging up.
