薛兰 / Xue Lan (late Han)
薛兰 / Xue Lan (late Han) enters the wiki through Hanji 986 as a 吕布 subordinate stationed with 李封 around Juye. 曹操 attacks them during the 兖州 recovery campaign and kills both, prompting Lü Bu to come to the rescue and fall into Cao Cao’s ambush.
The page is source-scoped. Xue Lan matters here mainly as the trigger for the compact pre-定陶之战 sequence: Cao Cao first removes local Lü Bu commanders, then uses the rescue response to recover momentum in Yanzhou.
