Fixing my faction after hunting gnomes in sol a?

[Melodyy]

Hi, I ignorantly took groups that hunted gnomes in sol a, and want to correct that faction. I went to the bank in Kaladim this morning and was killed by hi lvl Miners Guild 628 mobs there.

I see that I need to raise Miners Guild 628 and Deep Pockets faction. What's the best way to do that?

Thanks!
