Beloved pet of Charon's more unconventional counselor Waqas Jilani, Kahless has been thoroughly spayed, neutered and whatever else might be required to prevent the crew from having to deal with corridors filled with fluffy things. When he is not assisting the counselor by purring at patients, the surprisingly agile tribble can mostly be found in Charon's galley or carried around by Nohtho (the debate whether the Fvai thinks of the fluffball as a toy or pal is still open).
