Does the shipwreck from Rune's (from the Thieves Guild) past exist?

Rune is a character you meet in the Thieves Guild. When you speak to him, he tells you about his past:

As a child, Rune washed up on shore after a shipwreck near Solitude, and was found by a local fisherman. Rune could not recall his past, but the fisherman found a rock with strange writing on it. The fisherman named him Rune.

Rune spends all his money trying to find out about his past. Near where he stands, there's a letter addressed to him:

I looked all over Solitude, but I can't find anything in any of the shipwrecks, and the Internet is turning up a blank. Does this shipwreck actually exist - is there any way we can help Rune?

Solution 1:

Nope. There's no way you can help Rune.

There are a number of shipwrecks, and one of them might be the one in his past, but there is no explicit or implicit connection, and there is no loot or lore to indicate that this must be the case associated with any of them.

Solution 2:

when you talk to rune he mentions a ship that sank, i have found all of the ship wrecks and only one of them is under water. but its not near solitude. it the pilgrims trench. maybe its it but i havent been able to reach it, Imperial, and i can give you the location to, its to the west of winterhold and its deep under water. from what i can see from the surface its been split in two, and it seems to be that the current is going to solitude. im not sure but maybe its it.hope this helps, and if it dont it may behold tresure.

Solution 3:

According to the guide, currently, no.
