Bad spelling can be lethal. For example, the greedy Seriph of Al-Yabi was 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-Yabi are renowned
for being remarkably short and bad-tempered.
