Celestia is been called "CL". But I think it supposed to be CT. Heres why:
Wizard City (2 words) Krokotopia Marleybone (Two Words 'sound like') ____------ ---------____ Those means sound. This means Krokotiopia is sound like: Kroko-Topia.
Others have like two name combined too and Celestia pronouced: Ce-les-tia And 'tia' sound more like a place's call. So I think it should be CT.
