Got up a first post as both Jimmy and Peter. Hopefully they are fine.
I have two minor issues, but not enough to require an edit or anything. The first is that you had the ship enter the atmosphere in Wolverine's intro, though normally these Sentinels keep their ships in orbit and teleport down to the surface. However, I'm willing to overlook that and not require an edit since it is a small, trivial thing. My second issue is the Sentinels boarding the Excalibur, meaning a Traveler Scar is on a space station that has apparently only existed for a few months. If America had suddenly opened a star portal onto the Excalibur, chances are such an event would have triggered a massive security alert by the station's personnel and put everyone on edge. You mentioned there had been no incursions since the station was built, so it seems unlikely that any star portals opened on the facility once it was operational. However, I am willing to overlook this, and we can just assume that some part of the station was constructed using repurposed materials, perhaps a large piece of scrap metal that at one time was sitting in a junk yard somewhere and had a Traveler Scar embedded into it while America was passing through.
