So, let's evaluate who could have possibly caused the death of Esteemed notquitethere.
1) Some unlikely deathworld power use? A scum with a night kill ability died D4. If we presume basic use of the nightkill, no special extras, maybe possible. Also, this might get around things like a post restriction preventing kills? Since it might be an ability to target another ability, and itself not a kill. It could even be designed to work around the 'Esteemed' ability's limits, we've seen things in play hand-made to counter other things in play.
2) People who could have:
Esteemed Imp could have, with the inspection claim. Gets risky, to just go calling folks town without knowing, but there's nothing stopping Esteemed Imp from either some deathworld power use (if they have that) or some kill (if they have that, nightkill?) I also know this didn't happen.
Esteemed Maximum Spin might have a way to use others abilities that does not mean they are vulnerable to the limitations of 'Esteemed'. I think that would greatly amuse that one, to play with the entire idea of it, and use it to cover 'oh but I couldn't kill and now I can't protect, so that may be why there's more deaths even'. I don't think it's likely. I do think it's possible, and fits well with giving Esteemed Maximum Spin a 'make up for it' game role of their dream, even if it isn't cult.
Esteemed Secretdorf has not claimed a night action, and does appear to not have tried to steal a vote, leaving them free to do whatever?
Esteemed ToonyMan, as their claim of protecting Esteemed Imp cannot be verified by that worthy anymore, since not even possible status effects can be seen being gained and lost.
Esteemed The Canadian kitten, as their inspection of Esteemed hector13 cannot be confirmed.
Seems impossible to have killed:
Esteemed CrystalizedMire, unless somehow able to act while banished. If so, would be through infestation of Esteemed Jim Groovester's gun, so they're here and not here at the same time? Seems unlikely and we have to have a way to get them back/kill them while they're gone.
Esteemed Lenglon could not have without being teamed with Esteemed Elephant Parade, who has to be teamed with others too, for they are claimed roleblocked and bombed. Unless anti-town team of 3 people there, impossible. This also means Esteemed Elephant Parade (the roleblocker) and Esteemed Jim Groovester cannot be the killer unless they are actually an anti-town team or or the mason pair are hiding a redirected kill, as they wouldn't kill confirmed town. I'm okay with ruling out these three as possible killer.
Esteemed Hector13, not even if redirected, as they are confirmed conferring Esteem to one of the masons.
