In this part we traveled to homeworld of krogans- Tuchanka. We wanted to know if our adopted krogan Grunt has some illness. Guard told us to wait because clan leader is busy. At the same time we saw who leader was- our old buddy Wrex. He was talking with another krogan but then saw us and rushed to greet us. After seeing us alive Wrex was very happy. He also had an ambitious goal he said that he is gonna unite all krogan. The other krogan called Uvenk tried to argue so Wrex headbuted him and told to shut up. After that we asked what is wrong with Grunt. Wrex said that nothing is wrong- Grunt is just becoming an adult so he has to do the Rite of Passage.
After that Wrex told us to to go see the shaman. We found Shaman arguing with Uvenk about allowing Grunt to do the Rite. Uvenk said that Grunt has no allies willing to kill and die on his behalf. So we did what Wrex did- headbuted Uvenk and told him that we will kill for Grunt. Our actions impressed Shaman and he allowed us to do the Rite of Passage. Shaman took us to the location of the Rite. There we had to do three trails. First we had to defeat a buch of Varrens. After that some alien creatures called Klixen spawned in the arena and we killed them as well. The last trial was really challenging- we had to face a Thresher Maw on foot. The big worm was spitting acid(?) and damaging our shields. Our objective was just to survive a few minutes but we managed to slay the Thresher Maw.
After that Uvenk came with a few his soldiers. NOW He was impressed by Grunt's power. The last person who killed Thresher Maw was Wrex. So Uvenk wanted Grunt to join his clan. We refused so it began a fight with Uvenk and his minions. We won. Then Shaman came and said that we passed the Rite. Grunt is now a full adult and is welcome to join clan Urdnot(Wrex clan).
