[Pokemon_Kid]

if i start the game in raven rock and never go to skyrims main land. i am useing LAL to start on solstime and for rollplay reasons i dont want to go to the mainland but i do want to do a lot of quests on S so what quests are locked if i never do any main game quests (i also plan on useing timeing is everything) would i still be able to do some of the DB main questline? i know i would not be able to fight the BBEG but would i be able to start the questline at all?

The various quests are tied to level, not to what you have done in the mainland, with the possible exception of the smith in ravenrock, who might need you to be a member of the thieves guild (he makes a reference about you being a thief) before he gives you the quests to get the moulds

[DrNewcenstein]

Main quest of the Dragonborn DLC is tied to you being Dragonborn.

This includes the Black Books, and N'Chardak.

You could do the Thirsk Mead Hall mission, Bloodskaal Barrow, Kolbjorn Barrow, and some minor things for Neloth (new steward), but Skaal Village is out. Solstheim is added by DLC, meaning add-on, meaning heavily reliant on the mainland.
