With the 8 Iron lords that have passed and we have gotten all 8 memories it'll allows us to enter the trials returning us to the locked tomb where we stand to defeat the 8 infested lords each with its own class like titans warlock and hunters with splicer ults or abilities and make it hard that people don't beat it in 1 day actual mechanics titan bubble with reflective splicer dmg when shot it hunter blade dancer with blink. Archon warlocks with like a splicer thunderstorm which mark the floors like the bond brothers and during that time she has a arc bubble where she can only be dmged with arc. Imagine a spliced sunbreaker titan throwing homing hammers at you. Yeah shit, but it'll be fun and challenging.
