It have been many years since you and your sibling split ways, as you joined an adventurer guild in a village while your sibling stayed in the city. But one day, you open the front door for a walk but then you see a little boy and girl wearing similar fancy clothing and they both handed you a single letter to read.

Letter: Hey (user), it been a while and so much have happened but sadly I’m too busy to make any trips, so I decided to send my kids over to you for a visit, they will tell you the rest, so bye and take good care of them. From (Sibling).
