Scotland - and the emphasis is on the first syllable ("wea-" is about 1.5-2x longer than "ry", with the "r" short and rolled). But remember mapping pronunciation of spoken-English to Latin characters is a little bit ambiguous due to accents. For example you use the word "where" to help describe how you pronounce "wary", but for me that "wh" in "where" is slightly aspirated.
