Galekh is a scholar of sorts, spending most of his time reading up on subjects of interest. His thirst for knowledge is what brings him to invite the player to his hive in the first place, as he is more than eager to understand more about aliens--specifically humans. Galekh has a large library with numerous books, and mentions that he'd spent quite some time researching aliens before inviting the player over in the hopes of getting more relevant information on the matter. When the player is happy to cooperate with Galekh, the blueblood asks numerous questions pertaining to human culture, which inadvertently sends the player into an existential crisis. Despite his extensive knowledge regarding certain topics, Galekh is open-minded and willing to gain new experiences by stepping out of his comfort zone.

While Galekh might appear to be a calm and confident character, there are times when he becomes ruffled by the player's actions. When the player either calls him out on his concern for impressions or repeatedly interrupts him, Galekh gets visibly agitated and annoyed. This implies that Galekh might be somewhat anxious in nature, since he's quite worried about what others think of him and feels the need to correct any misconceptions right away. This is best illustrated when the player unknowingly made a lewd remark when Mallek is working on Galekh's tattoo: Galekh lets loose an anguished cry and remains quite upset until the player tactfully resolves the tension in the room. It should also be noted that Galekh has a tendency of speaking in a rushed manner when unsettled, with anger biting at his words.

Even though Galekh repeatedly makes it clear that he simply wants to study the player for the sake of learning more about humans, the player is quick to notice that Galekh seemingly pays more attention to the player's ability to make friends. When confronted with the insinuation that he would like more pals, Galekh pointedly informs the player that he's not that desperate for companions. However, the player concludes that Galekh's defensive nature is meant to hide the fact that the indigoblood wants to be recognized and liked by others. After a bit of talking, Galekh more or less admits that being known for something other than his intellect would be alright. 

Despite his status as a highblood, it quickly becomes evident that Galekh isn't interested in keeping people hostage for cruel amusement--he outright states that he usually has better things to do. Galekh is very formal and courteous in nature, greeting those he meets with a brief introduction and a firm handshake regardless of social standing. Galekh also brews coffee for the player right after granting them entry into his library, revealing that he takes civility quite seriously. However, should one insult his hospitality by boorish behavior, Galekh will become more than displeased with the disrespect he recieves. It should be noted that Galekh doesn't have any inhibitions when it comes to swearing, though he more or less tries to keep it at a minimum. 

Galekh seems to keep his belongings in a disorganized yet purposeful manner, which makes the player wonder whether he'd done so just for the sake of pointing interesting books out for them. Even so, Galekh is quite protective of his books and manuscripts: he expresses vague irritation with his custodians penchant for snacking on important tomes, and Galekh outright forbids Mallek from looking through his entire notebook. 

I'd imagine him sounding like the stereotypical college professor or a male version of Garnet from Steven Universe.
