"What? Oh I guess that makes sense..." He closes his eyes and takes a few deep breaths and then keeps reading, silently.
Trainee [name skipped] is lifebonded to Vanyel – lifebonds are a rare, poorly-understood magical phenomenon where two people are instantly deeply in love and also share magical reserves in some specific way – and also now the sole heir to a contentious border landholding and a future Herald. Queen's Own Lancir talks him out of some sort of ill-advised revenge plot via Mindhealing. Through some complicated decision-making process, it's then determined that he (and Savil, and Vanyel, and it turns out Savil's two other students) should be sent to said landholding in order to figure out succession before someone manages to start a civil war. There was a foreign mage for hire involved and this is apparently a bad sign.
They don't get to find out if the plan-as-specified would have worked, because the foreign mage in question turns up again and kidnaps Vanyel. The fastest-able-to-move of those present, the Heralds and trainees, take up a search, which turns into an unexpected battle in the woods with wyrsa, magically-changed monsters suspiciously brought in from elsewhere. It's a bit hard to follow what happens next, because Vanyel is not focusing very well and keeps skipping lines by mistake, but [unnamed trainee] peels off to look for Vanyel, finds him, is cornered by wyrsa, and attempts an emergency Gate out. This is a very challenging spell that he shouldn't actually be powerful or trained enough to do, but he gets instructions from his Companion and is able to draw on Vanyel's life-energy as fuel. He gets most of the way through and then his Companion, who's been trying to hold the monsters off, dies.
He finishes the Gate, shoves Vanyel through, and casts Final Strike, turning all of his life-energies into a very large fireball which takes out most of the landholding.
This is, unsurprisingly, not very good for Vanyel. It's briefly mentioned here that people generally don't survive losing a lifebonded partner.
Somewhere in the process, probably via having Gate-energy violently backlashed through him when a student takes the Gate down with poor technique, he ends up with both a large number of very strong uncontrolled Gifts and an allergy to Gates in particular.
Vanyel puts it down. :Can I stop now? There's more and maybe it's important but...: He trails off.
