Feature: Old Alliances Die Hard

You still have political power from the near royal to royal blood that you possess. While you are in the realm of influence of your royal to near royal blood you get free housing. Furthermore if you are on good terms with those in power of your bloodline you get a stipend of 300 gold pieces a week as spending money. You have advantage on checks that it would take to call a favor directly from your high noble or royal blood line or those of an ally of your blood line.

Feature: Protective Guardian

When you left you didn't leave alone. You might not have much money but you have a retainer. However unlike the retainer of other classes they are much more capable and can actually fight. They are almost always completely loyal. The retainer can have class levels which start at 5 then don't progress until you are level 10 staying four levels behind yours. If you take this option you have on tenth the starting gold you would initially have. You and your dm can decide more on the nature of the retainer. Maybe the retainer is just someone that gets you items, maybe they are a caretaker, maybe they are a holy warrior sworn to serve you, or whatever your mind can come up with.

Feature: Magical Item Stow Away

When you left you did so under the cover of night and you took something important to the crown. Because of this theft you might even have jeopardized your birthright. Either way you possess a powerful magical item. This was so important that it was all you took and you even perhaps burned some bridges to get it. You start out with no gold but the DM creates a magical item of rarity rare or higher for you to have. You are still either very close to royalty or royalty so the people searching for it won't try to kill you but they want to take the item back. They might try to take you back as well and put you under house arrest till they believe you learned your lesson. If the player has the magic item taken from them they may then try to get one of the other features instead but still lose the starting gold after they repair relations with their family.
