Domains: Propagation, continuity, gold.
Era of ascension: Great Expansion (~3,000 BSD). Cohort: current. Bylzar rose as maritime trade accelerated across Alaria; the expansion's merchant networks became his prayer base.
Worshipped by: Merchant guilds, trade-house bankers, moneylenders, and those whose livelihood depends on commerce continuing without interruption. (The worships edge is authored downstream on the worshipper, not here.)
Bylzar's domain of continuity means his followers are among the most resistant to poaching by rival daemons — they worship him precisely because things endure. Talressses once attempted to redirect a share of Bylzar's following toward himself; Mjulya intervened, and the gambit collapsed.
What his worshippers ask for is the long arc. A banking house wants to be the same house in a hundred years that it is today, the name unbroken, the ledger handed down intact; that span is Bylzar's domain, and the great merchant dynasties of the Middle Sea keep him because the dynasty itself is the prayer. Gold is his because gold is the thing that outlasts the man who earned it. The cult sits underneath the financial system rather than inside any one transaction — it does not care whether next month's delivery arrives, only whether the house that promised it is still standing a generation on.
That is the line between Bylzar and the rising contract-daemon Foedros, and the two do not compete because they are not after the same thing. Foedros is the single enforceable signature, the deal sealed this week. Bylzar is the house that will still honor the deal when the signer is dead. A great many notaries and bankers pay both, the contract-god for the document and the continuity-god for the dynasty, and see no conflict in it. The whole financial layer runs on exactly that division of labor.
The variant spelling "Blyzarch" appears in older halfling liturgical texts from the Sestros region — an in-world pronunciation drift retained as an alias.
