Child of the burrows, Simsa again finds herself abandoned on a desolate world. As she struggles to hold fast to her fierce independence, she continues to be forced from time to time to rely on “The Elder One”, a Forerunner spirit of the Simsa of a long dead remnant of a civilization predating even the remarkable Zacathans. Simsa and Zass (her one and only trusted companion) find themselves yet again with fast dwindling supplies she was able to salvage from the wrecked lifeboat while they search for any kind of shelter on a hostile and increasingly dangerous world. Even after finding a sanctuary of kind, Simsa continues her struggle to maintain her sense of self and not to be snared in yet another trap depriving her of her freedom, even if it means she may perish in the attempt.
