Mechanics disclaimer: Although Sariel is PH1 race (eladrin), and a PH1 class (warlord), as currently built she has a lot of feats, powers, and items from sources other than the books you listed. Also note there are some things (like alignment and languages) that do not show up on the plain text summary from the character builder; I've attached a PDF of her character sheet, which also has the full text for all of her powers. The iPlay4e sheet has links to all her powers at the compendium; I changed it to a hyperlink because the BBcode was designed for WotC's forums and a little off here, and because it made edits really slow.

background:
Sariel was the daughter and only heir of an eladrin noble who despaired of her obsessive interest in all things martial -- from stories and legends to training manuals and true histories of war -- despite being short, not very strong, and a passable archer at best. Nonetheless, she managed to charm her way into an adventuring company where a few well-placed words of encouragement and tactical pointers -- and that she would cheerfully patch up their injuries after battle -- seemed to cover up the fact that she very rarely managed to do any damage with her rapier.

synergy note: Sariel is a 'lazy' warlord; almost all of her powers grant basic attacks to other characters (and if she has to attack herself, it's a very bad sign). So having a good basic attack will mean your character works better with her.
