Blood's Meadow is not named after any living thing in particular. It is named after the crimson stains that have accumulated over the years. Before the Alpha of Issarak claimed this area as his, the pack that inhabited this stretch of land lived here. This was where they pitted their prisoners against each other in a form of amusement. Even when there is a fight to be battled out, the Alpha may request it to be held in Blood's Meadow, if it is anticipated enough.
