I'd say if you want to metal magic a door open, to first find a failsafe. If you can't find some other ic reason to keep Donny from just ripping open doors, we can get one of the mutiny's magic users to put wards in place and activate them at the start of the mutiny so as to significantly decrease the effectiveness of his magic. We don't want to debilitate the actions your character can take, but we also want to be careful to preserve some of the ooc organizational framework for this plot (in this case, the team who ultimately gets the doors back online) so things don't get completely out of hand as we go. If that's something you'd like to pursue, I'd ask that you keep us updated so we can iron everything out and make sure things roll as smoothly as possible without undermining the team selected for door duty!

Per your follow up question: absolutely not. Though this is a mutiny, the mutineers are absolutely not trying to hack and slash their way through the base. Taking the transporter room is hardly the most diplomatic route they could've taken, but they are not actively out to harm Transports (or even Initiative members as the whole reason they're taking the transporter is because it's literally the best bargaining chip they have - moreso than hostages could ever be). While actions of the community in response to the mutiny may spur them to become more physically aggressive, the initial reasoning behind taking the transporter is simply to force the Initiative to share power more equally and to begin to firmly establish a Transport-run leadership system that's more equal (or even more prevalent than) the Initiative leadership AKA putting people in leadership positions that, to the mutineers, feel more cohesive and actually have an element of control to them than, say, DITR etc.
