Shavri accepts the mental 'hand', and - doesn't feel any particular way - about the glimpse through her daughter's Othersenses of Leareth's mind to Mindhealing-Sight. There's something there, but it's a garden on fire and nearly all the plants are already gone. She takes Brightstar's offered rapport as well, and - focus inward, downward -
It's the weirdest fucking way of using Healing-Sight that Shavri has ever experienced. She has her Sight focused on something, but she can't pull back her mental viewpoint or shift the scale. She can see this structure, and if she effortfully refocuses she can end up on that structure instead, and her Sight seems to be under the impression that none of the structures in Leareth's body are in any way related to each other.
Blasting his shoulder joint with Healing-energy is not going to do anything useful, even if she could technically aim at it right now. If this is going to work at all, she needs to get herself focused on his heart and see if she can smack it around hard enough to get it beating, it doesn't even need to be an effective heartbeat that successfully moves blood, she just needs the energy-loop to exist at all so she can hook her Gift into it...
...Okay. That sure is a heart that is not doing anything. Seen up close, there's still a little bit of life-force there - it's not completely dark, and Shavri can make out structure, which she's pretty sure doesn't work on dead flesh. (It's historically been inconvenient for research, actually, that Healers can't train Sight on dead bodies, and can't cut up their living patients to look at how things are put together, so it takes a lot of drawings and practice to correlate them.)
Shavri throws a focused dart of Healing-energy, and -
- it lands, and it drains away and it's gone. Some of these cells are technically in some sense still alive, but they're - in living patients there's something like a cup, something Healing-energy can land in and propagate on from. The others are cracked cups, with both Healing-energy and their own natural life-force slowly but constantly leaking away.
This is a cup with no bottom. She can throw Healing-energy at it, sure, and at a hyper-local level there's something still there that can use it as fuel, but - there's nothing that can hold it even for a moment, let alone distribute it, and so most is pointlessly wasted. Shavri can't get a Healing-link to every cell in Leareth's body independently.
If she had something to replace the critical vital functions, routing around the damaged pathways entirely, so she could slow down and figure out what can still be repaired– ...but Healing-Gift doesn't work like that.
She tries again anyway, but she doesn't think it's going to work. She's pretty sure that all she's figured out, here, is an extremely creepy way to make Healing-Sight work on a recently-dead corpse.
