Star Trek-Ragnarok is a fan comic series by SSKamui about a conflict between 2 intergalactic empires the Federation gets involved in. During the conflict, Earth is rendered nearly uninhabitable by a Bioweapon, a cloud consisting of mushroom spores. Only a small part of earth could be saved by a shield generator. The last hope of humankind seems to be an old starship relic called Ragnarok which was found by Starfleet scientists a long time ago, but this ship seems to have sentience and killed all of the old research team.
