At the end of the conversation, Lancet left understanding a few things.
Astensia and Thor felt constricted inside the Summon Space. The feeling must have only worsened with the introduction of Espel and the fact that she, unlike them, got to live in the real world and continue with living as normal.
However, their situations were different. Espel wasn't dead before Lancet summoned her. In factuality, Astensia, Thor and Spectra were meant to be grateful to Lancet for even summoning them.
And they were.
But Lancet couldn't help but feel a little guilty even though there wasn't much he could do about it for now. Bound Summons and Invocated Summons worked differently.
With Bound Summons, Lancet didn't have to spend a lot of Grace since they were already anchored and present in the world. But Invocated Summons had to be anchored to present reality, which meant spending a lot of Grace.
