Greetings, and welcome to Letters From Tamriel!
The categories (see the menu in the right column) are grouped primarily by individual character, and the posts for each character proceed sequentially from the oldest date forward. You can begin by jumping into the blog feed, but I would recommend going to the posts tagged “<Name> – backstory” to read about a particular character’s premise and background; the individual letters will make more sense that way. If you’re interested in Issa, for example, the post tagged “Issa – background” will give you her starting concept. Another approach is to use the “Character Cast” category to hop to a collection of “background” posts for all characters.
The remaining, non-character categories (“About This Site”, “ESO news & info”, etc.) are from me as a player, not speaking in character voice. Those posts do not need to be read in any particular order.
Thanks for stopping by and encouraging my obsession. 🙂
