When your PC has a unique ability that helps out with the current major, year-long plot, this is what’s known as an RP hook. People who have their characters ask yours to use their ability are trying to include you in things.
But, by all means, continue to complain on channel about how nobody wants to play with you (and maybe you’re just a bad writer who should pick another hobby) and are just using your PC for their ability, all the while having said PC sit by themselves, speak in a language most other characters don’t know, and be passive aggressive whenever anyone with IC rank tries to be friendly.
