ISK sink

An "ISK Sink" refers to any mechanic where ISK leaving a players wallet is not going into another players wallet, i.e. the ISK is being absorbed or destroyed by a NPC entity.

This causes deflation within the economy, as ISK leaves the universe, but the amount of goods in it remain the same (or increase).
