Lake Segra (pronounced SEG-rah) is a large lake in Matarsah. A large island within the lake contains a small lake of its own, around which a major wood giant community, Segra Kana, has grown - this recursive lake has no widely accepted name of its own.
The shorelines of the lake are a mix of tropical forests, much like the rest of Matarsah, as well as some mangroves that long ago find a niche in the freshwater environment. Predators and prey alike hide in these areas, but none threaten the giants, who are simply too large to be reasonable targets.
