sustainer
One who maintains
A sustainer is someone or something that maintains, supports, or keeps something going.
The word appears most often in religious contexts, where God is described as the sustainer of life or creation.
In rocketry, a sustainer is an engine that maintains thrust after booster stages separate.
More broadly, anything that provides ongoing support qualifies: Music was her sustainer through difficult times.
