The alliance is as follows: First of all, Galko, the dark spirit-binding man in Stormwind, has received the task of "looking for Steinhard". From Storm City, he took a Griffin to Yese Town, ran from Yese Town to the goblin harbor of Thorn Forest, and took a boat to Ratchet City, where Steinhard was on the right mountain.
Then Steinhardt asked you to go to the library of Ironforge to find krom thick arm, which is the top of Ironforge. Krom's thick arms let you look for broken conspiracy books: broken manuscripts will randomly appear under the huts of seven or eight fishermen on the west coast of Nanhai Town; Take a boat from Minel Port to Selamo Island, take the elevator through the barren land (there are two orcs on both sides of the elevator, which should be solved first), and reach the Chiba jungle. Found moldy books in the tellurium fort on the right side of the elevator.
Back to Ironforge, krom's rough arm talks. He told you that Steinhardt asked you to take three XXX wands (I can't remember the name, anyway, it was clearly written in the mission) to kill the orc mage of the Dragon Throat clan (I couldn't find such a monster, but I got it by killing the guards of Dragon Throat XX in the wetland angry tooth camp). After getting three wands, go back to Ratchet City to find steinhardt, and then follow him into the house. He and his disciples will release the summoning array.
BL's demand for tasks and articles is similar to LM's, but the people who hand in tasks are different.
