Series time line.

[Farseer]

so, it seems we've fairly well placed both the Farseer trilogy, the tawny man books and the rain wild books.

Farseer would be first, with tawny man being placed some 15 or so years after it. for the most part, about 5-6 years pass before rain wild.

I am disagreeing with you beings on this one, and a few below, as some events in TM happened concurrently with events in the Rain Wilds, and even previous to the commencement of the RWC (we share at least one significant event with the RWC characters that we know has already taken place at the very beginning of TM. Will have to revisit this to back up my answer.

It would not be all that unlikely that the Liveship books are several years after the Farseer books, considering that (spoiler)
[spoiler="tawny man & liveship class spoiler"]Fitz not only visited the rain wilds, but also went to bingtown, without encountering the fool. This means that the fool would not have gone to the rain wilds instantly.

put say, 4 years into that part. Then add in a small break between his leaving and the fool, a.k.a. amber coming south. Add a couple of years for amber to settle in before books start. That makes about 7 years. The liveship books take a few years to pass, say three. That brings the total to 10 years. This would indicate that tawny man starts 5 years after liveship ends. This seems a bit odd, as the information spread to the duchies about the rain wilders work with dragons is neither correct nor reliable. Even in a society as disconnected as RotE, at least some reliable information ought to have filtered north in a span of five years. perhaps shifting liveship ahead a year or two would be more likely.

perhaps asking the tangle leader is the solution?[/spoiler]

I actually got the feeling that *major Farseer, LST and TM spoiler*

Spoiler

Fitz was drawn to Bingtown and particularly Rain Wild Street as this is the region where Fool was at the time. It was only the magic of the street that prevented him from actually venturing down it...much the same as how he avoided the path of Others' Island. Fitz was also drawn back by the land which was calling him, namely Kelsingra etc, and this calling saw he and Nighteyes attempt their trip up the Rain River, but I think Fool's presence there was also drawing him, given their (by then) well-established Skill link/bond.

The two years I previously spoke of, from the end of the Red Ships War to the indirect meeting up of Brashen, Althea and Amber outside Amber's shop, was the two years that it took for Amber to find her feet in Bingtown, selling her wares in the small shop before relocating to Rain Wild Street. We are not privy to what took place in those two years but Brashen had noted that, up to that point where he and Althea had seen her in her shop window, Amber had been settled in Bingtown for two years. Likely she fled there after Regal had attempted to confer lands and a title on Fool following his actions in leading the simulacra back to Buckkeep etc.

I could wallow like a pig in this forever but life calls. Hopefully it will not be long before I can wallow some more...and maybe do some more disagreeing with those beings known as 'thul. Fun that.
