Martel will be cooperative and straightforward in recounting what he remembers; he didn't see the rift opened but like Jamie, felt the shard react. Went out to deal with it, saw two other rifters, led them through the first attempt to close the thing, was joined by several others (he doesn't know any of their names, offhand, as Martel has negative eighty interest in other rifters) who worked in tandem. He remembers up to the barrier he cast around Jamie and Church being broken by a demon, and after that he'll be frank that he'd overextended himself and his head was on fire with spell backlash, his memories are a pain-fog until the following day when he woke up in his bed.
