I see myself and many artists like me as the torchbearers through these dark ages.

This quote means that the speaker views themselves as a leader and guide, like a torchbearer in a dark time. They believe that they have an important role to play, along with many other artists, in helping to lead people through a difficult period. They feel that they must set an example, bring light and hope to others, and create art that inspires and helps people cope.
