John W. Howell asked about the Caster Swamp, which is a central setting for several Legends of Windemere books. It is a dangerous place where unique monsters roam and thrive. It is also the home of the Lich who rules over it with pride. So, where did the swamp and its creatures come from?
Well, it was rather benign and simple in the early days. A few witches and monsters called it home until the Necrocaster Council took over. They sectioned off the swamp and built great towers and castles where they ruled for a couple hundred years. This created more variety of monsters and earned the name of Caster Swamp. They attempted to conquer the surrounding region, but were beaten back by the Gaian forces. This caused them to stay in their towers and create undead and monsters to protect their home. Still, it was not until the Lich appeared that the area became very deadly.
It is unclear how he defeated the Necrocaster Council, but it didn’t take long. Many believe the Lich absorbed all of them, but there are those who think he transformed them into monsters that wander the swamp. None of the servants of the former masters survived the battle. One incident occurred where people thought the Council returned and forces went in to attack, but all they found were creatures that had been previously unheard of or thought to exist in other regions. This was a trick by the Lich to demonstrate his power and he used the battle to finish a ritual that enchanted the Caster Swamp to grow when Visindor Forest is weakened.
To date there have been no real changes to the Caster Swamp, but it remains one of the deadliest areas of Ralian. There are safe zones created by forest trackers, but they don’t go very far into the area. So going beyond those outposts means you’re either going to die or come back with a few parts (and sanity) missing.
