The deepmere leviathan is the great filter-feeder of Lumen Hollow's deep water, a translucent mountain of flesh lit from within by everything it has swallowed. It is gentle by nature and vast beyond fighting; the danger is not its malice but its indifference, for a startled leviathan can capsize an entire raft-market with one roll.
