Bad spelling can be lethal. For example, the greedy Seriph of Al-Ybi was once cursed by a badly-educated deity and for some days everything he touched turned to Glod, which happened to be the name of a small dwarf from a mountain community hundreds of miles away who found himself magically dragged to the kingdom and relentlessly duplicated. Some two thousand Glods later the spell wore off. These days, the people of Al-Ybi are renowned for being unusually short and bad-tempered.
