Hear ye, hear ye! Unbeknownst to some, Sampersand hath also created Squire, a companion language to ye lowly language Knight. Squire hath many possessions, but alas, it doth not golfeth as well as its brethren. Thou shalt check it out as well, though.

I cannot provideth thee with a demo link yet as the interpreter is a very lengthy incantation.

Ungolfeth:

# Createth a variable known by most as "n",
# He shalt begin his journey as a mere
# peasant with naught but the value zero.
n = 0
# Loop thine program unto n approacheth C
# (Behold! Squire permits thee to write numbers
# in Roman numerals)
whilst C > n {
    # Lo! I spotteth another variable,
    # who goes by the name of "t".
    # It shall start off as a lonely empty string.
    t = ""
    # Increase n's wealth by bestowing upon it the number one
    n = n + I
    # If n divideth evenly into 3...
    if !(n % 3) {
        # Replaceth t with the string "Fizz"
        t = "Fizz"
    }
    # If n also divideth evenly into 5...
    if !(n % V) {
        # Accompany t with the string "Buzz"
        t = t + "Buzz"
    }
    # Proclaim to ye standard output...
    proclaim(
        # Either...
        (
           #  t if it is not a lonely empty string...
           t
           # or n, converteth to ye foreign Arabic
           # number system, used in lands afar.
           || arabic(n)
        )
        # Appendeth upon it a newline to start
        # another journey.
        + "\n"
    )
}

The preferred output format useth string(n) in opposition to arabic(n), which displayeth n in Roman numerals, but nay, thy great quest beseecheth that we must use this strange and unusual number format.
