"If all has gone well you'll have the stone in hand; we'll need the steel, and you said you can convince her to reshape it into an anchor. If not, anyone in the family can make plow shares."
so I think this is in reference first to the stone of nightsong, then to how he thinks he can convince thaisha to reforge the pariah blades into something new, and if not her any lloy would do.
"Once it's done, the next step is to bring it to the field. Our wings are leading a charge across the border to draw the locals from the site. That hot shot I mentioned will meet you there and help prepare the arch from steel to stone. Please try to temper his confidence with pragmatism. Yes, I know you are precisely the wrong person for that."
so if this is still referring to the most recent thing, the field would be the hallowed round, mara would be drawing tachonis souls from the other side, but I don't know what bogery would be doing except maybe preparing a way to faerie? i don't know what the "arch from steel to stone" means in this regard.
"Still, remember, until a stable trinity of bridges are built it is vital that the blood be protected. I trust that you have disguised it well. With any luck, the next time I see your face we will have undone the damage of our first attempt. More than one door will be open to us from there."
we watched the bridges get built! we watched the bridge from the river in the afterlife to araman to faerie get built in real time and then thaisha further connect it to the path. they even reopened faerie.
"Until then, I search for suitable anchors for the remaining four. We may need more hands soon after."
anchors for the other four shapers! so i think that what thjazi was doing was gathering the swords that felled the shapers, turning them to plowshares, and using their psychopomps to undermine whatever the tachonises were doing and freeing the souls that are trapped in the endless limbo of the underworld.
we know he had the blood, the pariah blades, and the ritual at the hallowed round. he had the stone of nightsong and probably a bead on the arrow that killed sylandri. and he had the coffin of obalad, already reshaped with a mask of the panto in it prepared for rauwyn (also happens to know a mask of the panto just bopping around the city)
for tansul he would need a tachonis (so lucky his sister in law is friends with occtis) and the staves of night (weird he went to tanessar with mara on a scouting mission the very place tansul was slain), we don't know with what or how trozhna, omra, or illumi died, but i will mention illumi's consort was the father of waves and we know someone who had a pact with a sea entity/a sea door has been mentioned.
i think the swords are the things that slayed the shapers and they are the items that need to be turned to plowshares. i think the anchors are the remains of the psychopomps, and i think each needs a ritual to reopen a door to an afterlife that has been closed. and i think the reason that the tachonis family wanted him dead so bad is this threatens their endless supply of souls in the afterworld, as does the Old Path, the only way for the souls to move on. i think this was thjazi's big plan to heal the world.
also, i think the professor is a member of the cloak who works at the totality.
