Before long, Rain realized that things were getting cold outside, and soon he found some pretty big icebergs on the ocean… the last time he had been there, he only found small ones, so that was suspicious.
"The level of mana in this area increased," Rain thought while looking around. "I wonder how that can happen naturally. It can't be a natural phenomena... then again, the enemies knows a lot more than me."

When people die, their life force and mana spread on the land, but if they are killed, a part of it goes to the killer, that is why they get experience.
