Wait a minute… NO ONE SAID THE SUMMONED SLAVE WOULD BE ONE THAT WAS SUFFERING!
the entity said:
1. the skill will summon a slave from around the world;
2. The summoned slave will be freed freed upon summoning;
3. The skill has a 7-day cool down
I understand that we're talking about slavery, but the elf doesn't look that traumatized about being a slave. She was afraid of the sword, okay, but in this world, everyone would be afraid of an unknown subject carrying a sword.
The "if theres a slave suffering" talk doesn't work here because we have no proof that the summoned subjects will be "suffering" or mistreated ones.
If the next slave shows up like how tsuareninia was when Sebas Tian first found her, then this talk applies
