Is there a canonical reason why Sol was dripped out in the middle of the Holy War during his greasy trash man era?

Do you think Kliff gave him an allowance and one day and he went into town then came back Riot branded head to toe? Do you think Riot sponsored the Holy War?

I like to imagine Kliff put him in charge of the month’s funds for food and Sol spent it all on his designed Riot Holy Order Uniform. Then Kliff said “Haha Sol you have spent all of our money we will now starve” and then it was a really awkward month that made Sol decide to leave the Order

Post-Begin to post-Crusades Sol basically doesn't have any lore so you can just say whatever and it has just as high odds of maybe being true some day tbh lol

Sol was a bounty hunter before joining the Holy Order though. Probably he rolled up with fat stacks of cash, they showed him the uniform and he was like "fuck OFF I only wear red," and then had his boys over at Riot make him a custom tailored Holy Order uniform with its stupid fingerless-not-fingerless gloves with steel fingernails with RIOT stamped on them

but then Sol didn't have any money left over and ate all the Holy Order's food and Kliff said they will now starve anyway
