The Muster Rolls of Fellbarrow Pass

The war-marshal of Fellbarrow Pass is raising sellsword companies against the raiders on the high road. Each company that answers the horn is entered on the muster roll as one line: the company's name, how many blades it brings, and the holdfast it is sent to guard. The scribe has fallen to a crossbow bolt, and the marshal will pay a fair purse to whoever can write the lines in the proper form.

Write musterCall(company, blades, place), where:

• company is a non-empty string, the company's name.
• blades is a non-negative integer, the number of fighters the company brings.
• place is a non-empty string, the holdfast the company is sent to.

Return a single string of exactly this form:

<company>: <blades> blades bound for <place>.

The rules are:

• Write company and place exactly as given, with no change to their letters or spacing.
• Write blades as an ordinary whole number.
• Use the word blade when blades is exactly 1. For every other number, including 0, use blades.
• There is a colon directly after the company name, single spaces between words, and a full stop at the end.
